Plants and photosynthetic algae and bacteria use energy from sunlight to combine carbon dioxide (C02) from the atmosphere with water (H2O) to form carbohydrates. These carbohydrates store energy. Oxygen (O2) is a byproduct that is released into the atmosphere. This process is known as photosynthesis.
Photosynthesis consists of light-dependent and light-independent reactions... as we all know, the reactants of photosynthesis are carbon-dioxide, water and light, and the products are carbohydrates and oxygen... But which reactants and which products are the components of which of the 2 reactions.... The LIGHT-DEPENDENT reaction needs LIGHT in order to split WATER, to give OXYGEN as a byproduct, and the ENERGY (in the form of ATP and NADPH) necessary for LIGHT-INDEPENDENT reaction to take action.
